INTRODUCTION

1.1 Description of the V6 Series

Spellman’s V6 Series is a family of regulated, fixed

output polarity module high voltage power supplies which
provide exceptional performance and value in many
applications. Utilizing proprietary power conversion
technology these SMT based high voltage modules
provide improved performance, reliability and easy
system integr ation. T he V6 series units are fully enclosed
and designed for system or bench top operation.

The V6 is rated at 30 watts with output voltages spanning
from 1kV to 30kV with fixed positive or negative
polarities. Voltage & Current loo ps with automatic cross
over control regulate the output into any load condition.
The output voltage is controlled locally by an internal
multi-turn potentiometer. Remote analog voltage and
current programming capability are included in all
models. Analog monitor outputs are also included for
remote monito ring of outp ut voltage and current. The V6
is a reliable and robust series that is arc a nd short circuit
protected. The comprehensive standard interface provides
interfacing flexibility and all V6 units are CE, UL and
RoHS compliant.

1.2 S t a nda rd Features

The V6 Series incorporates several standard features
designed to optimize user satisfaction and safety:

●Current Regulating Loop: Current programmability
allows the user to set where the unit will current limit,
anywhere from 0 to 100% of maximum rated current.

● 0 to +5Vdc Remote Programming Inputs: Positive
polarity, high impedance, ground referenced 0 to 5Vdc
voltage programming inputs correspond to 0 to 100%
rated voltage and current outputs.

● Local Control: Multi-turn potentiometer located on the
top of the unit is provided to control the output voltage
locally.

● 0 to +5Vdc Monitor Outputs: Positive polarity, low
impedance, ground referenced 0 to 5Vdc voltage monitor
outputs correspond to 0 to 100% rated output voltage and
current.

● Precision +5Vdc Reference Output: A precision

micro power band gap reference of +5Vdc, ±0.5%,
25ppm/°C is provided to simplify remote programming of
the power supply.

● Arc and Short Circuit Protected: Due to the fixed,
high frequency conversion rate the V6 series output
capacitance is small resulting in minimal stored energy.
Through the use of generously rated surge limiting
resistors and a fast acting c urrent loop, all units are fully
arc and short circuit protected.

1.3 Re m ot e Ope rating Features

● Enable Input: The Enable Input allows the user to
easily control the HV ON/OFF status o f t he power supply.
HCMOS compatible signals A low (<1.5Vdc) enable
input signal e quals HV ON, w hil e a high (open or >3 V d c)
enable signal equals HV OFF.

Warning!

The Enable Input should not be used as

protection against user injury or for a safety

interlock function.

1.4 Option

RS232 interface is available

V6 Series MANUAL 1 118130-001 REV C

1.5 Interpreting the Model
Number

The power supplies model number describes its
capabilities. Model numbers are configured as follows:

U6A30P30RS where:

V6 is the product series name
A is for AC input voltage and D for DC input voltage
30 is the maximum output voltage in kV
P is the output polarity
30 is the output power in watts
RS is for RS-232 interface (omit RS for analog interface)

Interface

X numbered units are unique units custom developed for
specific application requirements above and beyond the
scope of the available standard options. Each 4 digit X
number corresponds to an applicable specification control
drawing.

INSPECTION & INSTALLATION

Initial inspection and preliminary checkout procedures are
recommended. For safe operation, please follow the
procedures described in Chapter 3, Operating Instructions.

2.1 Initial In spection

Inspect the packaging exterior for evidence of damage
due to improper handling in tr ansit. Notify the car rier and
Spellman High Voltage immediatel y if damage is evident.
Do not destroy or remove any of the packing material
used in a da maged shipme nt.

After unpacking inspect the power supply for any visible
signs of damage.

2.2 Mechanical Installation

V6 units ca n be mounted in any position using the tapped
holes in the base plate. 8-32 screws are required for
mounting. Please see the V6 series data s heet for a more
detailed dimensional drawing.

2.3 Temperature Consideration

It is the user’s responsibility to maintain the case
temperature below 50°C. Damage to the power supply
due to inadequate cooling is considered misuse and
repairs will not be covered under warranty

Operating In structions

3.1 Operation

WARNING!

This equipment generates dangerous voltages

that may be fatal.

Proper grounding of all high voltage equi p ment

is essential.

It is highly recommended that all testing comply

with IEEE Standard 510-1983 IEEE

Recommended Practices for Safety in High

Voltage and High Power Testing. A copy of this

standard can be downloaded from the Spell m an

High Voltage website

INPUT VOLTAGE

Check the identification label on the power supply and
confirm it matches the input voltage of the so urce suppl y
that will be used to power the V6 module. T he DC units
operate with +24Vdc ± 10%, 2Amp. The AC units
operate from 90Vac to 264Vac 50/60 Herts, 1Amp

HIGH VOLTAGE CONNECTION

Insure that high voltage connection is properly terminated
to the load. Co nfirm that adequate air isolatio ns spacings
exist for the maximum voltage of the power supply, using
the guideline of 10kV per inch (25.4mm) to any points
that will be elevated to high voltage. All acce ssible high
voltage points should be enclosed in a protective Faraday
enclosure. Any access panels on the safety enclosure
should be interlocked.

V6 Series MANUAL 5 118130-001 REV C

here.

GROUNDING

Proper grounding of the unit is essential for reliable
operation. Power Ground, Signal Ground and HV Ground
Return are connected internally.

The Power Ground connection (J1 Pin 13) carries the
+24Vdc current that powers the unit. Make this
connection adequate enough to handle 2 amps, minimum.
Additionally it is recommended that this connection be
used to tie the power supply to whatever potential is used
as the local “system ground”.

Signal grounds relating to programming and monitor
functions should be referenced to the V6’s Signal Ground
(J1 Pin 6).

A physical load return connection must be made from the
bottom of the load to the power supplies HV Ground stud
(chassis).

See Figure 2 for DC modules details.
See Figure 3 for AC modules details.

OPTIONS

See Section 5 of this manual for RS-232 Communication
Protocol. Custom X numbers units may also require
special test requirements; con sult the unit’s specification
control drawing for details.

SIGNAL CONNECTIONS

Connect the appropriate programming and monitoring
signals to the unit as detailed in the figures in this chapter.

INITIAL TURN ON

A) Set t he voltage and current p rogramming inputs

for zero output (J1-4 and J1-9 respectively).
Open t he Enable Input (J1-8), to a ssure the unit
is in HV OFF mode.

B) The DC or AC input power can now be

connected.

C) Enable the power supply by grounding the

Enable Input (J1-8).
